Problem 11DQ

In uniform circular motion, how does the acceleration change when the speed is increased by a factor of 3? When the radius is decreased by a factor of 2?

Step-by-Step Solution:

Solution 11DQ Step 1 of 3: Centripetal force is the force that is acted on the object in circular motion, which is directed towards the center. As in figure below For a body in circular motion,the acceleration is centripetal acceleration which is defined as the rate of change of tangential velocity as in figure below The expression for the centripetal accelerationca ) is, ac= v2 r Where v and w are the linear and angular velocity of the object and r is the radius.
